Comment on Automatic reconnect in MySQL Connector/Python? by Geert Vanderkelen

@Joe The example in this blog post is not a 'solution'. It shows a possible way of using the reconnect()-method. How you use it is totally up to you.

“Would the above use case of reconnecting be enough?”

So, let me get this straight… your proposed solution is for me to back and wrap every one of my cursor.execute() statments with the 14 extra lines you’ve suggested?

Blog is not a place for discussions. Please use the MySQL forums: http://forums.mysql.com/list.php?50

Note that ‘with_rows’ means that the query you execute _could_ return rows. It doesn’t mean it ‘has rows’. It is meant to distinct between SELECT and INSERT for example.

sorry…many questions

I am puzzled about with_rows. “This read-only property will return True when the result of the executed operation provides rows.” — from RefMan But, as follow is :

query = (“select name from test_innodb where age > 100″) ## empty rows

for result in cur.execute(query):
if result.with_rows:
print (“Statement: {0}”.format(result.statement))

I found result.with_rows was always True if query is just SELECT statement whose result is empty or not.

Thanks,

ya..it is cool

this afternoon I also tried lastrowid like MySQLdb. It is excited to me that *SHE* is already there :P
rowcount is also available even though it is yet to document.

thanks,

@zhang It is.. indeed not in the documentation. That's something we need to fix. However, it is part of PEP-249, and it is a cursor property called 'lastrowid' Example: >>> import mysql.connector >>> cnx = mysql.connector.connect(.......) >>> cur = cnx.cursor() >>> cur.execute("INSERT INTO t1 (c1) VALUES ('ham')") >>> cur.lastrowid 1

Hi Geert,

mysql-connector-python dose not support last_insert_id yet, right? I could not find any function about it in refman.

Thanks,

Comment on Fetching rows as dictionaries with MySQL Connector/Python by Geert Vanderkelen

@Thomas Unicode is important, so better start getting used to it. In Python v3 strings are Unicode. That said, in Python v2, simply use 'use_unicode=False' as connection argument, or use .encode('utf8') on the result.

Hi Geert, I'm searching quite a while to get rid of a certain problem, maybe you could help me... You wrote: The above results in an output like this: 1 [{u'c1': datetime.datetime(2010, 10, 13, 8, 55, 35), u'c2': u'ham'}, {u'c1': datetime.datetime(2010, 10, 13, 8, 55, 38), u'c2': u'spam'}] Now you're output is in unicode and I like it to be just printed to the screen as normal text. My question to you is if you know how to convert it or to get rid of the unicode characters?? Thanks!
